This video covers IB Chemistry subtopics 4.2 & 4.3 from the IB Chemistry topic 4 syllabus content.
This video begins by reviewing the main energy levels, and how valence shell behaviour is governed by the octet rule and the expanded octet rule. Then, the steps for drawing Lewis structures are covered, with several examples, before introducing VSEPR theory and how electron domains determine the geometries of molecules. The video ends on the discussion of the structures and properties of the four major allotropes of carbon.
00:00 Introduction

01:11 Octet rule
01:33 Expanded octet rule
02:11 Drawing Lewis structures
